Thanks a lot. I am to used to C and, more important, I didn't think to look for 
also another operator for the power function :)

Oh, and I forgot to mention that this is doing what you probably asked for 
originally:

```d
import std;
import cmath = core.stdc.math;
void main()
{
    // both print 1e+72
    writeln(pow(10.0, 72));
    writeln(cmath.pow(10, 72));
}
```

But it's just floating-point scientific notation, not true BigInts.

Another math difference from C is that D has well-defined wrapping math for 
signed ints.
